Everyone pronates! Contrary to popular misconception it is healthy and normal. The problem begins when one or both of our feet pronate too much. When the arches flex too far inward or stay collapsed
for too long pronation is considered excessive. We call this overpronation. Overpronation is by far the most common foot type. Pronation is not linked one-to-one with low arches. Although pronation
lowers the arches, this does not mean that only those with low arches overpronate. People with high arches can also overpronate! Some of us have always overpronated, for others overpronation develops
with age, weight gain, regular standing work or intensive exercise.
Excess stress on the inner surface of the foot can cause injury and pain in the foot and ankle. Repeated rotational forces through the shin, knee, thigh and pelvis also place additional strain on the
muscles, tendons and ligaments of the lower leg.
It is important to note that pronation is not wrong or bad for you. In fact, our feet need to pronate and supinate to achieve proper gait. Pronation (rolling inwards) absorbs shock and supination
(rolling outwards) propels our feet forward. It is our body?s natural shock-absorbing mechanism. The problem is over-pronation i.e. the pronation movement goes too deep and lasts for too long, which
hinders the foot from recovering and supinating. With every step, excess pronation impedes your natural walking pattern, causing an imbalance in the body and consequent excessive wear and tear in
joints, muscles and ligaments. Some common complaints associated with over-pronation include Heel Pain (Plantar Fasciitis) ,Ball of foot pain, Achilles Tendonitis, Shin splints, Knee Pain, Lower Back
When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation,
or more commonly known as shin splints.
Non Surgical Treatment
Over-Pronation can be treated conservatively (non-surgical treatments) with over-the-counter orthotics. This orthotics should be designed with appropriate arch support and medial rear foot posting to
prevent the over-pronation. Footwear should also be examined to ensure there is a proper fit. Footwear with a firm heel counter is often recommended for extra support and stability. Improperly
fitting footwear can lead to additional foot problems. If the problem persists, consult your foot doctor.
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with
fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
